Dear Razzman79,
Sorry you’re unable to access your Personal Vault files on your Mac. Personal Vault is not available directly through the OneDrive app on macOS, so it needs to be opened through a supported web browser.
Reference: Protect your OneDrive files in Personal Vault
Please try the options below and check whether the issue continues:
- Update macOS and your browser, then restart the Mac.
- Open OneDrive on the web using the latest Edge, Chrome, or Firefox in a private/incognito window.
- Temporarily disable any VPN, ad blocker, or privacy extension, then try unlocking the Vault again.
- If available, select another verification method, such as Microsoft Authenticator, text message, or email code.
- Try accessing Personal Vault on a different device to check whether the issue is specific to your Mac.
If the issue continues, you can create a temporary user account on your Mac and test OneDrive Personal Vault there to check whether something in your current macOS profile is interfering with the sign-in process.
- Open System Settings > Users & Groups.
- Select Add User and create a temporary standard account.
- Sign out of your current Mac account and sign in to the new one.
- Open the latest Chrome or Edge, go to OneDrive online, and try opening Personal Vault.
Check this Apple’s detailed guide to add a user on Mac. You will need an administrator account to create the user.
